Moja dziewczyna szybko przełącza się na tryb masturbacji, gdy ogląda porno

I'm scared my girlfriend won't need me anymore now that she's discovered she can just watch female masturbation porn and jerk off without me. I mean see how she's comfortable doing it herself following a tutorial better than anything I can offer. It's just a matter of time before she gets a dildo and she won't need me for penetrative sex anymore.
